Specification 6: Letters Patent.

Patented May 27, 1913.

Application filed January 2. 1912. Serial No. 668,868.

To (It! whom it may concern:

Be it known that I, lIANs LOUIS Jensen, a citizen of the United States,residing at Dayton, in the county of ltlontgomery and State of Ohio,have invented certain new and useful Improvements in Printing- Presses,of which the following is a specification, reference being had thereinto the accompanying drawing.

This invention relates to printing presses and more particularly toprinting presses designed for printing bills or other forms, theproduction of which requires a series of printing operations. Forexample a bill of lading requires four separate n'inting operations, itis printed on both sides, the successive bills are consecutivelynumbered and a red ink number is printed on the face of the bill toindicate whether it is an original, second or third copy. In additionthe bills are punched to form therein he desired apertures. As nowconstructed many of the machines which will produce these bills are verylarge and not only occupy much valuable floor space but are veryexpensive. Moreover, the arrangement of the usual machine is such thatthe printing rolls and the cooperating parts are not readily accessible,the setting up of the machine or its prepw ration fpr printing a givenform being rendered very ditlicult.

The object of the present invention is to 'pwvidc a press to produceforms or bills requiring a series of printing operations which will bevery compactly arranged so that it will occupy a relatively small amountof space; and which will have its printing rolls so arranged that theywill be readily accessible and of such a construction that the platescan be quickly and easily attached to and removed from the same, therebyenabling the machine to be quickly and easily set up for a particularpiece of work.

In the accom )anying drawings, Figure 1 is a section ta (on just insideone of the frame members and showing the gearing carried by both framemembers in dotted lines; Fig. 2 is an elevation of the printing rollershowing the means for attaching the plates thereto in section; Fig. flisan end view of the same; Fig. 4 is an end View of the lower sectionthereof; and Fig. 5 is an end view of the upper section thereof.

In these drawings l have illustrated one embodiment ofnn' invention andhaveshown members of the respective couples in an up the same ascomprising a frame formed of two upright members 1, only one of which isillustrated in the drawings, the other frame member. being a duplicateof that here shown. The frame is of a relatively great height and, inthe present instance, its height is considerably greater than itslength. At its front and rear ends the frame is provided with supportingdevices for paper rolls, that device at the rear end of the frame beingadapted to support the supply roll from which the paper is fed to thepress and the device at the front end of the machine being adapted tosupport a rewinding roll upon which the printed forms are wound. Whilethese supporting devices may be of any suitable character I have showneach as comprising a pair of arms 2 mounted on a transverse shaft 3mounted in the side members of the frame. Each of the arms 2 of eachdevice, of which but; one is here shown. is provided at its free endwith a half bearing 4 adapted to receive the end of the su 'iportingshaft 5 for the paper roll 6. Mounted upon the frame in a fixed positionare segmental bearings 7 arranged t t} cl'itipcrate with the halfbearings 4 of the arms to retain the rolls in position when the arms 2are in their upright position. A lever 8 is rigidly se ured to the shaft3 and by manipulatin; this lever the arms 2 can be lowered into asubstantially horizontal position and the roll of paper rolled betweenthe arms with the projecting ends of the shaft in a position to be cn ued by the a to half bearings when the arms are elevated, thus causingthe elevation of the arms to lift the roll into its proper position, asShown in the drawings.

Tn order to arrange the mechanism as compactly as possib e and at thesame time have the parts thereof readily accessible I have arranged themechanisms which act upon the paper-about the edge of the frame, and thepaper as it is guided through the several mechanisms from the supplyroll to the rewindihg roll travels in approximately an inverted U-shapepath. The present device comprises three rotary printing couples, eachcomprising a printing roll and a platen. Two of these printing couplesare arranged near the front and rear ends of the frame. respect ively, are mounted in such positions that the paper will pass between the twoward and downward direction, respectively. and are. so arranged that theprinting roller is reuilily accessible A. third priiningcouple iarranged near the top of ihe frmne :illll is so mounted that the paperwill puss between the two nu rulers of the couple in :1 enlist-2n tiullyhorizontal plane. The first pr nting ouple which is arranged near therear edge of the frame comprises a printing roll 9 and a platen 10mounted on shafts ll and 12, respectively, which, in lurn, are mountedin bearings formed in the frame near the edge thereof. The axes of thetwo nnernbers 10f the couple are arranged transversely-t0 the height ofthe machine but an an irr lination to the vertical. This arrangementpermits the paper to pass upwardly between the two members of the simpleand the same time supports the printing roll, which. in the presentarrangement, is the upper roll. in such a pcsiiion that it is reudilyac.- essible to the operator. One of the rolls is movable relatively tothe other To inrow off the impression, and, in the present in stance,the platen is mounted in an eccentric bearin 13 which permits it to bemoved away om the printing or form roll. The inking mechanism for theform roll is of a known character and is indicated as 21 whole by thereference numeral 14-. The paper is guided from thesupply roll betweenthe two members of the printing couple by passing the same first aboutguide rollers or drums 15, thence about; a guide 1.6, thence between thetwo members of the couple and about a guide 17 from which it extendsupward about another guide l8 carried by the ink ing mechanism, thenceto the second couple which is similar in construction to that. justdescribed and comprises a platen 19 and a printing roller 20 arranged toprint on the opposite side of the web from that printed upon by theprinting roll 9. The axes of the two members of this rotary couple. arear anged in an approximately vertical. plane so that. ihc paper nillpass between the same in a transverse direction. The )lzinc of the axesof the two n'icinbers lies between inc paper roll supporting devices andthe print ing couples wl'iicl'i are arranged iil'iovc the some and thusrill ws the psi-is lo lrc. compnctly arranged, The ihiiwl printingcouple comprises :i platen J1 and a painting" roll 22. This latter roll,however, not the ordinary form r ll but 1' moun ed thereon :1 eri s ofliliiilll cs adapted i'o print cmisccutive urmliers upon iii sneer-s ivebills or forms as they pus; beluwcn the two members of the. printingcouple The (letuil c nstruction of this numbering device is not. :1 partof lhe prlw wt inventi n and llifiltl lil'tl, not lierilv l'i urel indetail, ll. being sulli icnt for ilw pur 'm e of ilH presei'lt'inwnti nto sizilv that the two members of the couple are rolury and in theirbroad aspects are similar to the rotary members oi the other printingcouples. The inking devices for ilic second and third printing coupics,which are imlicatcd ii! 93 and 24, rcspcctively, are of ordinaryconstruction and require no description in connection with the presentin vcnlion. A punching device comprising two rotary meml'iers 25 and 26adapted to form the desired perforations in the bills is mounted in theframe between the third printing couple and the re'winding roll 6. Hereagain the detail construction of. the punching devices is not 2. art ofthe invention and is not here described, it being sufficient to statethat these punching devices comprise two members rotatable aboutparallel axes.

The several operating devices may be driven in any suitable manner butpreferably by trains of gearing mounted upon the two side members of theframe and connecting the several moving parts with a suitable source ofpower.

It will be noted from the, foregoing description that the printing rolls9, 20 and 22 are arranged in such positions that they are readilyaccessible from the exterior of the machine. To further facilitate thesetting up of the rolls 9 and 20, that is, the applying thereto of theprinting plates, I have so constructed these rolls that the plates canbe quickly and easily clamped thereto. To this end I have divided eachroll longitudinally to form two sections, the lower section being hereindicated by the reference numeral 2 andv the upper section by thereference numeral 28. The lower section is mounted on the shuf, which.in the use of the first couplc, is indicated by the reference 11 and theupper sectimi 28 movably connected to the. lower section. Preferablythis connection is a hinged one and is formed by a longitudinal hingepin 29 extending throu h aperturcd lugs on adjacent portions oi therespective ctions of ihe roll.

The iv'o sections of the roll may be moved relatively one to the otherin any suitable manner to expand and contract the roll. in the presentinstance I have shown a link 30 mounted on a stud 31 rigidly secured toone end of the upper section 28 and extending across the adjacentsurfaces of thctwd sections of the roll and mounted upon an ecwntric pincarried by a stud 33 journulml in ie lower section 27 of the roll. Thepin 32 provided on its outer end with a nurwl .u Ill adapted to reccivcu wrench to enable ll'ustud to be rotated. It will be zip iizreui hatthe rotation of the stud will w ciztiic pin to more rclulirely l-r-ciion oi the roll and, conseiii i nlr. will be actuated to more the uri-r i l relativ ly to th lower se iion. ln u, the parts may be lockedIV have provided in iiirir :2

the link with an extension extending beyond the stud 33 and havingtherein a slot 35 to receive a cap screw 36 which extends into the endof the roll and by means of which the link can be locked againstmovement relatively to the lower section of the roll, thereby lockingthe two sections in their adjusted positions. Suitable clamping membersare mounted on the exterior of the roll l and cotiperate therewith tohold the plates in position thereon. In the present instance theseclamping members comprise rings 37 extending about the roll and havingop-l positely extending flanges 38 adapted to extend over lips orprojections 39 formed on the ends of the plates, which are shown at 40.The arrangement of the two sections of l the roll is such that when intheir expanded i positions they will form a substantially true cylinderand conform to the inner circumference of the plates. The clamping ringsthat when the sections 37 are of such a slze have been expanded intosubstantially true cylindrical form the projections 39 of the plates"will be held firmly between the flanges on the clamping rings and thebody of the roll, thus quickly same in position.

and easily securing the 1 It will be understood that 1 the plates areformed of substantially semi- 1 cylii'idrical form and are placed inposition 1 on the form and the clamping rings slipped 1 over theprojections on the ends thereotl The (it of the parts is sufiicientlyclose to l retain each plate temporarily in position. i The nextadjacent plate is then slipped into position on the other side of thering and an- 1 other clai'npin 7 ring applied to the opposite end untilall t e plates are in position. The roll is then expanded and theseveral plates clamped in pla e. all of which can be done very quicldyand easily. This mechanism combined with the readily accessiblepositions of the form rolls enables the forms to be rpiiclily and casilyapplied and adjuslcd on the rolls and results in a grcal saying of 1time and labor orcr the system now com m nly in usc.

ihi- Hlflljll'lflli of thc device will be readily ur rslond ir n: theforegoing description au l it will be appai'cnl that thc machinci nhichl have prodiiccd irof a rcry ompa t arrangement. \hc parts being mountedin such a manner that the organized machine occupies but a small am untof space: and further that the several parts are readily a essible fromthe cxlcrior of the machine and are of such a character that they can be1 cxtcri r of said sci-lions and quickly and easily manipulated toprepare the machine for operation.

'While I have shown and described one embodiment of my invention it willbe und'erstood that this has been chosen for the purpose of illustrationonly and that I do not desire to be limited to the details ofconstruction shown and described, for obvious modifications will occurto a person skilled in the art.

Having thus fully described my invention, what I claim as new and desireto secure by Letters Patent, is:-

l. A printing roll comprising a plurality of longitudinal sec'tirmsmovably connected one to the other, means for moving one of saidsections relatively to the other, and clamping rings extending about theexterior of said sections and adapted to engage the printing plates,whereby said plates may be clamped to said roll. i

2. A printing roll comprising two longitudinal sections pivotallyconnected one to the other, a link piyotally connected to one of saidsections. a pin eccentrically mounted in the other of said sections andextending through said link, whereby the rotation of said pin will moreone of said members toward or away from the other, clamping ringsextending about the exterior of said sections and adapted to extend overthe edges of the printing plates, whereby the ex pansion of saidsections will cause said plates to be clamped between the sections andthe rings.
